Description

Technical Field

[0001] The utility model belongs to the technical field of lathes, and particularly relates to a fixing tooling for a numerical control vertical lathe. Background Technique

[0002] The fixing tooling of a lathe usually uses a four-jaw chuck. The chuck is a mechanical device on the lathe used to clamp objects, and the parts processed by the lathe have a wide range of uses. Compared with the traditional mechanical four-jaw chuck, it requires workers to manually turn the screws inside the fixing device with a wrench to move the chuck inward to clamp and fix the object. After processing, the workers manually turn the screws inside the fixing device with a wrench to move the chuck outward to unload the object. For each object processed, there are steps of manual clamping and manual unloading. The above not only increases the workload of workers but also reduces the production volume of the workshop, greatly increasing the labor intensity of workers and causing workers to spend time and effort on loading and unloading materials.

[0003] When workers process objects, they need to manually turn the screws inside the fixing device with a wrench to move the chuck. For each part processed, there are steps of manual clamping and unloading, and the objects cannot be processed flexibly and conveniently. Therefore, the workload of workers is increased.
